I recently upgraded, with no problems, from Windows 7 Pro x64 to Windows 10. At first, my Twonky server (which supports just a Marantz M-CR510) was fine - now, it seems to disconnect and restart 10 seconds into the first track I play.

This manifests in the Explorer Network display thus - the "Music Library" (Media devices) and Twonky-Proxy and Twonky-NMC-Queue appear and disappear rapidly. Often, the Marantz just gives up and says "No network connection". It's now three days since I could play anything, and I'm stuck. Am reasonably proficient with Windows and home networking; before I unistall everything, can anybody suggest what might be happening? There's no hints in the event log of anything amiss (that I can find). I've trued with upnp enabled and disabled, it makes no difference.

Further information to my initial notification. In my Windows Network display, Media Devices, Marantz M-CR510 is permanently visible; it is the Music Library and the two Twonky "other devices" that continuously appear and disappear.

Update @ 16:22 BST. Same as usual, I can play 10 seconds of one track, and then the music server reloads. Log attached. Log entry times seem odd? No, it seems logging was already on, and the latest entries read
